Figure 1
Representative high-resolution scans for three types of reflections. 300 and 0-3-2 comply with parity rule h − k = 3n, while 42-1 disobeys the rule. Moreover, the 0-3-2 reflection shows micro-splitting because of the misalignment of tiny kaliophilite domains. Note that the abscissa has the same scale in all cases and λ = 0.6888 Å.
